1. If you are at sea several kilometers away from land, the most important thing is to conserve your strength. The most effective way to swim long distances is to swim sideways, saving your body for the waves that hit the shore around the island. The surf on the Pacific islands is very powerful. The power of the waves and currents is very strong. It is difficult to even climb the reef, so it is very difficult to go ashore. These rough rip currents are created by huge waves bouncing off the reef. Every year, 150 swimmers drown in rip currents in U.S. waters, draining their energy rapidly as they swim against the rapids. So the best way is to swim parallel to the coast until you can't feel the pull of the rapids, so you can swim ashore smoothly, preferably breaststroke, because this way you can keep your head above the water, looking for the best export.
2. When you are on a deserted island, it is best to first explore the island to see what natural resources are there.
3. When climbing, first find the best route with the most grip points and footholds. Use your arms to guide the direction, and use your legs to push hard.
4. If you see coconut trees on a desert island, you can go to the place where there are coconut trees. Coconuts mean water and food.
5. Bamboo is very versatile, it can be used to build shelter, make spears, and many other things that are crucial in survival.
6. Find a shelter from the wind on a desert island.
7. There are many deserted islands in the Pacific Ocean. When you are stranded on a deserted island, there is a high probability that someone is looking for you, so to ensure that you can be found by the rescue team, you need to build a beacon as a signal. To burn the fire as big as possible, use flammable fuel, to burn quickly and vigorously, you can use some dry pine needles as a kindling material, and then use a large piece of dead coconut tree branches to surround the pile of kindling materials. Get your stuff ready and order it when you see a boat or plane. Spread the fresh coconut branches and leaves on the outermost periphery, it can not only waterproof, keep the beacon dry, but also emit smoke. If someone passes by during the day, the effect of smoke is better than that of fire.
8. There is a technique called fire tillage, which is widely used in the islands of the Pacific Ocean. Hibiscus, which grows all over Polynesia, is a perfect wood to use as a base for a fire, because it has a low moisture content, by creating enough friction between the wood handle and the groove of the base to start a fire, and then you can get some Burning shavings, which are used to light a kindling from coconut trees.
9. While keeping warm isn't an issue, the sun can be harsh and prolonged exposure to wind and rain can also damage your health, so make a simple shelter. Hibiscus is a widely used wood that is very popular on Pacific island coastlines. Common, you can recognize it by its heart-shaped leaves, and its smooth bark is a good material for rope.
10. Shelters are usually built in the shade, but on a desert island the priority is to see you in the air so that the rescue team can be called, so build a shelter on the beach.
11. Build a shelter on the island. The first layer is to use dry coconut leaves, and then cover the top with fresh leaves. They are more waterproof.
12. Survival is not only a physical test, but also a psychological test. Sometimes a simple thing, such as taking a bath, can cheer you up.
13. The reason why many islands are uninhabited is because there is no ready-made water source, so the best way to find something to drink is to pick some coconuts, but the coconut trees are very tall, about 10 to 12 meters, and it is not easy to pick coconuts. . A specific technique for climbing coconut trees is to keep your feet and toes under pressure on the tree trunk at all times, and alternately move your feet and hands as you climb up (a position similar to riding a horse). The key is to have strong legs. If you ride well, you can climb coconut trees. To pluck the coconut is to keep rotating the coconut, twisting. Coconuts can be a lifesaver in the case of a shipwreck, but they can also kill you, and every year someone is killed by a coconut hit in the head. The blue-colored coconuts are fresher, contain far more water than the old brown coconuts scattered on the beach, and are more nutritious. Coconut is rich in potassium, which is lost in large quantities when your body sweats, and it also contains vitamin C and carbohydrates, so it is a good source of energy.
14. You can use bamboo to make a harpoon to fork fish. In order to prevent the bamboo pole from splitting, you should use some hibiscus bark to tie the bottom section of it, and then cut the head of the bamboo and cut it off slowly, so that you can cut it. Out of four sharp spearheads. It can also be used for self-defense, as these waters are also hunting grounds for sharks. But fishing is dangerous, some fish are poisonous, some attack you, keep your hands away from any dark nooks and crannies, because moray eels will attack anything that comes into the world, and you can't eat them, they will be poisoned.
15. Humans have the lowest breath-holding ability of all mammals, but gradually become longer than at the beginning.
16. A plant can be used to poison fish. This tuber plant is found throughout the Pacific region. It has unique oval leaves and grows near the coastline. The toxin is in its roots. The fresh, tiny roots are the most poisonous. When the tide is low, fish are often trapped in small reef ponds. You can crush this piece of rhizome, squeeze out the oil from it, and then rinse the roots in the water a few times. After a few minutes, the fish in the small pond will come to the surface. The plant and its roots contain rotenone, which can kill the fish but is harmless to humans.
17. To steam the fish, they can be baked in a shallow pit, which is a traditional Hawaiian stone oven. A pit is first dug, and then the fire is burned with the large tongs made earlier. The hot stones are sandwiched and placed in the pit, and then these stones are hot, these stones can continue to heat for several hours, and the sand is a good thermal insulation material. Wrap the fish in some tea leaves (tea leaves also have medicinal properties and are great for anti-aging), they make the food tastier and retain all the moisture. Finally, take some fresh large leaves and put them on the bottom of the grilled fish, put the fish in the middle, then cover with two large leaves, and finally cover with sand. After about an hour, you can eat it. The protruding eyes of the fish indicate that already cooked.
18. Mash the coconut meat to extract the oil, which can protect the skin from the sun and sea water.
19. Outriggers can be added to the canoe to increase stability, but it is more complicated. It is possible to build a catamaran, a raft with two hulls that is not that complicated, but also very stable. Bamboo is very useful for sailing, and it is often used to reinforce and increase buoyancy. There are many air pockets between the knots of bamboo, and even the bamboo itself has tiny air cells. Because the knife can never cut the bamboo, to bring down a bamboo you need to light a fire at the bottom, but you must pierce it before that. One of these airbags, because these bamboos are air-filled airtight cabins, if you don't do that, the air will be heated and expanded after ignition, and the bamboo will explode directly, so you must pierce it first to balance the air pressure inside and out. Interweave coconut leaves to make a sail, then make a wooden frame to hold the sail.
21. The waves are usually very regular. They are usually in a series of seven, and in this series, the waves are larger than the other. With patience and careful observation of wave patterns, you can avoid the biggest waves.
22. A good way to collect rainwater is to fold a piece of old coconut bark into the shape of a canoe, put it on the beach, put a large leaf rainwater on it, and the rainwater will stay down its stem.
23. Before rafting, prepare sand for sharpening knives, because if you see a boat, you can use the knife as a signal mirror.
24. The number one problem encountered at sea is the sun. Can hide under the sail with a little shade. And the sea water soaked in the body, the whole body is wet, the skin will become very dry. Apply coconut oil to the skin to prevent damage from these seawater and sun exposure.
25. The way to stay cool is to jump into the sea for a dip every few hours, but make sure you're on a rope or you might lose your raft, and you must check carefully before jumping into the water for sharks. When swimming in the sea, you must wear good clothes and shoes. When a group of people are in the sea, those without clothes are often the first to be attacked, because sharks will mistake the reflection of sunlight on their skin for fish. Of all the sharks in the sea, the tiger shark bite is the most destructive, and if you are attacked by a shark in the water, the best way to deal with it is to yell, slap the water, hit his nose, or it The gills, the most sensitive part of the shark's body. With the exception of the great white shark, tiger sharks have been recorded to bite more people than any other species of shark, so be vigilant.
26. You can use fish bones as hooks, hibiscus fibers as fishing lines, and bamboo as fishing rods.
27. When you see a boat at sea, you can use the reflection of a knife to signal. Sharpen it on the sand with a knife to make it brighter, then stretch your hand in a V shape, let the knife shine in the sun, aim it at the target, let it sway back and forth in the field of vision, pray over there Anyone on deck can see. Such a signal can be seen as far as 16km away.
